A power feeding system of the present disclosure includes a control unit. In a case where a magnitude of supply destination power is smaller than an upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power based on power output from the power source, and to charge the storage battery with power which is a difference obtained by subtracting the supply destination power from the upper limit value of the power supply capability of the power source. In a case where the magnitude of the supply destination power is more than or equal to the upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power by both the power source and the storage battery.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The power feeding system according to claim 1, wherein the control unit controls the charge/discharge control circuit so as to change the power supply capability of the power source to be allocated to charging of the storage battery based on a state of charge of the storage battery and the magnitude of the supply destination power.
3. The power feeding system according to claim 2, wherein the control unit controls the charge/discharge control circuit so as to further change the power supply capability of the power source to be allocated to charging of the storage battery based on an environmental temperature at a place where the storage battery is installed.
4. The power feeding system according to claim 1, wherein in a case where the forced charging instruction is provided from the user, the control unit controls the charge/discharge control circuit so as to perform charging until the storage battery reaches a full charge, and provides the user with a charging completion notification in response to completion of charging of the storage battery.
5. The power feeding system according to claim 1, further comprising a solar panel configured to supply the supply destination power.
